As we know that using of electronics devices as well as communication devices is increasing as time is increasing in our daily life. The main reason behind the increasing of demand of electronics devices is that these devices are portable in nature. Everyone buy a electronic gadget by thinking of one factor in the mind which is mainly power consumption of the electronic devices. There is also need or requirement of every person to scale down the power consumption of different devices present in electronics and communication engineering, along with power generation is also a big task. The device which is mainly used to reduce the power consumption of various devices is through the presence of comparator. As we know in present time every analog device is converted into digital device. So we can do this with the help of comparator. So comparator is a device which convert analog signal into digital signal. In my paper, I present a review on the various low power and high performance comparator as well as power dissipation of the different comparator under different temperature on 90nm, 180nm and 250 nm CMOS technology. The main parameter which we considered in the paper are power dissipation of different types of comparator such as conventional single tail comparator, Double tail comparator, modified double tail comparator and comparator with cross couple inverter.
